www.pharmtech.com n the manufacture of many pharmaceutical products, dry-particle blending is a critical step that directly affects content uniformity. Tumbling blenders—a common way to mix granular constituents—are hollow containers attached to a rotating shaft; the vessel is partially loaded with materials and rotated. Their main advantages are large capacities, low-shear stresses, flexibilit...

Myanmar has one of the largest malaria burdens in the Greater Background: Mekong Subregion (GMS). Throughout the GMS, Plasmodium falciparum parasites are increasingly resistant to artemisinin combination therapies. Given that there are no current alternative treatment therapies, one proposed solution to the threat of untreatable malaria is to eliminate the parasite P. falciparum from the region...

In this paper, we introduce a new algebraic structure, called a UP-algebra (UP means the University of Phayao) and a concept of UP-ideals, UP-subalgebras, congruences and UP-homomorphisms in UP-algebras, and investigated some related properties of them. We also describe connections between UP-ideals, UP-subalgebras, congruences and UP-homomorphisms, and show that the notion of UP-algebras is a ...

A long-range goal of qualitative physics is to develop systematic models that capture the breadth and depth of human reasoning about the physical world . Such models will be crucial for future intelligent computer-aided design and tutoring systems . Clearly, they will need to be orders of magnitude larger than today's models . Furthermore, they must capture phenomena at several levels of detail...

the health sector, a foremost service sector in nigeria, faces a number of challenges; primarily, the persistent under-funding of the health sector by the nigerian government as evidence reveals low allocations to the health sector and poor health system performance which are reflected in key health indices of the country.notwithstanding, there is evidence that the private sector could be a key...

An analysis of a scaled-up version of IGNITOR (to a major radius of 2.16 m) is discussed. The design, referred to as DIGNITOR, is a direct extrapolation of IGNITOR. The consequences from the increased size are discussed (mainly due to decreased temperature excursions). A summary of comprehensive calculations of the stresses (documented in an accompanying paper) are presented. The case of a dive...

Bayesian networks are widely used graphical models which represent uncertain relations between the random variables in a domain compactly and intuitively. The first step of applying Bayesian networks to real-word problems typically requires building the network structure. Among others, optimal structure learning via score-and-search has become an active research topic in recent years. In this c...

Spray drying is presently one of the most interesting technologies in the pharmaceutical industry. The process shows a remarkable capability in manipulating powder/particle attributes such as size, morphology, density and level of residual solvents. This flexibility led to its application in a variety of powder formulations and advanced solid forms: from very fine powders for inhalation to larg...

A qualitative physics which captures the depth and breadth of an engineer's knowledge will be orders of magnitude larger than the models of today's qualitative physics . To build and use such models effectively requires explicit modeling assumptions to manage complexity . This, in turn, gives rise to the problem of selecting the right qualitative model for some purpose . This paper addresses th...
